For sleep apnea therapy patients who use oxygen supply units, the Oxygen Supply Adapter from AG effectively delivers supplemental oxygen through your CPAP machine. The adapter comes with a standard 22mm diameter to connect your oxygen supply to any CPAP, BiPAP or BiLevel machine. For CPAP masks equipped with a special oxygen port, all you have to do is easily attach the oxygen supply adapter to receive a steady oxygen flow throughout the night. Masks that do not have a built-in feature require a separate bleed-in adaptor that is compatible with your CPAP machine. For patients who struggle with low oxygen levels along with sleep apnea, the Oxygen Supply Adapter is the a, affordable solution.
